Details
An issue was discovered in Insyde InsydeH2O kernel 5.2 before version 05.29.50, kernel 5.3 before version 05.38.50, kernel 5.4 before version 05.46.50, kernel 5.5 before version 05.54.50, kernel 5.6 before version 05.61.50, and kernel 5.7 before version 05.70.50. In VariableRuntimeDxe driver, VariableServicesSetVariable () can be called by gRT_>SetVariable () or the SmmSetSensitiveVariable () or SmmInternalSetVariable () from SMM. In VariableServicesSetVariable (), it uses StrSize () to get variable name size, uses StrLen () to get variable name length and uses StrCmp () to compare strings. These actions may cause a buffer over-read.

Vulnerability from github – Published: 2022-05-24 19:07 – Updated: 2022-10-08 00:00
VLAI
Details
A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The Jt981.dll library in affected applications lacks proper validation of user-supplied data when parsing JT files. This could result in an out of bounds read past the end of an allocated buffer. An attacker could leverage this vulnerability to leak information in the context of the current process. (ZDI-CAN-13406)
